110 bcd double crankset

[James Bondra]

I just saw an article about Tyler Hamilton using a 110 bcd crank with 52
x 36 chainrings.

I am interested in a similar setup (110 bcd double) as where I live it
is very hilly and I am interested in doing a few 100+ mile rides with
10,000 ft of climbing. I am currently running a Campy Daytona 9sp double
front derailleur and a 9 speed double Daytona rear derailleur. I have a
clamp on front derailleur. Is it possible to run either a 52 or 50 and a
34 inner ring with this set up? I would prefer not to have to go the
triple route due to cost.

My questions are these:

a) With a front double derailleur what is the maximum tooth difference I
can run with chainrings?
b) What is the largest rear cogset? I am running a 13 x 26, but have a
13 x 28.

I am looking at Dimension Cross Crankset.

Thanks for any help you can give me.

sounds cool to me. my knees could use that as well, but I've taken the
plunge and gone for a triple.

Shimano 105, stuff, not too bad on cost, but it means you buying new
shifters.

Something to keep in mind that Tylers crank is made by Full Speed Ahead
(FSA) and is only available in carbon if its available to the public. They
used the 110 bolt size as this is the standard size for mtb chianrings so
that they could have a good selection of off the shelf sizes to choose from
for the stages. Also keep in mind, the cranks alone will set you back $250+!

Best of luck with the conversion...

TA make a 110BCD crankset (the Zephyr Light), Rivendell still have stock of
the Ritchey 110BCD double (made by Sugino) and also another Sugino 110BCD
double. You can get five arm 110BCD splined spiders to fit MTB cranksets
that have a removeable spider.

Why do you need a 50 or 52? 48-11 is almost exactly the same gear as 53-12.
I use 48-34 chainrings with an 11-23 10s cassette for road racing and 13-29
cassette for pottering around in the hills. And the Daytona derailleur has
no problems with the 29t rear sprocket.

I currently run a 48/34 on 2 Campy bicycles, one is 9 and the other is
10sp. Using a regular cage derailleur, I can run 12/23, 13/28, 13/29
w/o problem. I size the chain for 48/28 and just put in whatever
cassette I like. The shifting from 34 to 50 is difficult and 34 to 48
can be seamless with the proper front derailleur. A Campy 10 works
better than a Campy 9 and I have no idea as to why. A Shimano 105
works best. The large ring you select should have pronounced pins and
ramps.

I have an extra Dimension Crankset, 48/34 that I'd like to sell. I
bought it for my wife but she insisted on a triple I have the BB and
31.8 clamp derailleur too. You really won't need the bb because the
111 Daytona bb, ISO bb will work like the 107 JIT bb that is required.
Should you be a weight weenie, I have a ti World Class bb that is 110
that works with the crankset too.

No longer true.

So history has been somehow revised?

No longer *half* true.

I run a 53x33 110 double with a _standard_ 105 double front derailleur. It is rated for 14t but works just
fine for more.

I use the following combos (and others):

53x39 & 12x23
53x36 & 12x24
53x36 & 13x25
53x33 & 12x24
53x33 & 12x28
53x33 & 13x28

My r-der is a DA triple because I like the way it looks w/ the 13t pulleys.

Virtually no adjustments are necessary for changing the gears other than actually changing the inner ring
and/or the cassette.

Rivendell has a couple of different and nice 110 cranks (at different price levels). The Ritchey is a very
nice cold-forged crank that weighs in @ approximately the same as the 7402 DA crank.

50 to 36 is a bit more reasonable. Still a pretty big jump. I'd start with
a 48/36 and see if you can't cover it with that.

~12 - 14 tooth difference range is common on a double.

Determined by your rear deraulleur - you could go to a long cage and run a
11x32 if you can find one to your liking.

Dunno what the Dimension runs, but there's a nice Ritchey double that has
those specs - (just received the Riv paper catalog...)

Choices of large cog cassettes are limited and the jumps between cogs
like 18 to 21 are noticeable. A 48/34 with a 12/27 is about the same
as a 53/39 with a 13/32. You need no special rear derailleur and you
can use Campy hubs.

"Precious" and "Pup" eh? Well named.
